The swing seats of Bihar

There is a concept of swing states in the US. What are these? Well as the name suggests, these are the states that have had the history of changing loyalties. At times they have chosen Democrats, and then in the next elections, they went with the Republicans; hence, swing states.

The elections in the US and Bihar are no way similar, but the phenomenon of swing seats is. There are certain seats in Bihar, where voters have defied the so-called political narratives, waves or the general flow. These seats are key to both sides as apart from their bastion, winning these seats increases their numbers and chances to come to power.
